1. 去官網(wǎng)下載安裝包

下載鏈接：點擊打開鏈接

https://dev.mysql.com/downloads/mysql/

如果你的系統(tǒng)是32位選擇第一個，64位選擇第二個

也可以用wget 下載

wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.11-linux-glibc2.12-i686.tar.gz

解壓文件

tar -zxvf mysql-8.0.11-linux-glibc2.12-i686.tar.gz

2 移動壓縮包到usr/local目錄下,并重命名文件

mv /root/mysql-8.0.11-linux-glibc2.12-i686 /usr/local/mysql

3.在MySQL根目錄下新建一個文件夾data,用于存放數(shù)據(jù)

mkdir data

4.創(chuàng)建 mysql 用戶組和 mysql 用戶

groupadd mysqluseradd -g mysql mysql

5.改變 mysql 目錄權(quán)限

chown -R mysql.mysql /usr/local/mysql/ 或者 chown -R mysql . chgrp -R mysql .

注意最后有一點

6.初始化數(shù)據(jù)庫

創(chuàng)建mysql_install_db安裝文件

mkdir mysql_install_dbchmod 777 ./mysql_install_db

初始化

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data //初始化數(shù)據(jù)庫

或者

/usr/local/mysql/bin/mysqld --initialize --user=mysql/usr/local/mysql/bin/mysqld --initialize --user=mysql/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server in progress as process 5826 [Server] A temporary password is generated for root@localhost: twi=Tlsi<0O!/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server has completed

記錄好自己的臨時密碼：

twi=Tlsi<0O!

這里遇到了問題沒有l(wèi)ibnuma.so.1

zsh: command not found: mysqld
./bin/mysqld --initialize
./bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

2018-04-29 17:06:30 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2018-04-29 17:06:30 [ERROR] Can't locate the language directory.

需要安裝 libnuma

yum install libnumayum -y install numactlyum install libaio1 libaio-dev

安裝文件

7.mysql配置

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

修改my.cnf文件

vim /etc/my.cnf

[mysqld] basedir = /usr/local/mysql  datadir = /usr/local/mysql/data socket = /usr/local/mysql/mysql.sock character-set-server=utf8 port = 3306 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES [client] socket = /usr/local/mysql/mysql.sock default-character-set=utf8

esc保存

:wq 退出

8建立MySQL服務

cp -a ./support-files/mysql.server /etc/init.d/mysqld

cp mysql.server /etc/init.d/mysqlchmod +x /etc/init.d/mysql
